Problems with RAW - HELP!

Hi there,
I really hope someone can help me. I just got aperture. RAW files look bad on my mac. They have this oversaturated look. I use my nikon D70 to take RAW + JPEG and the jpeg looks good. BTW, it's the same problem in iPhoto. I uploaded converted jpeg of each the pictures:
JPEG: http://picasaweb.google.com/itai123/RawProblem/photo#4956805354384654354
RAW: http://picasaweb.google.com/itai123/RawProblem/photo#4956805355282956306
Thank you in advance for any help you provide, this is frustrating

Eduardo is correct to point out that the jpeg has already been processed by the camera. The jpeg file is a derivative of the RAW file so any information it displays has to be present in the RAW file.
The jpeg file conversion is chosen by the manufacturer of the sensor/camera and it will be a compromise for the best image that can be obtained because it will have to drop quite a lot of detail data to arrive at the processed file.
The RAW files will all need sharpening and possibly some exposure compensation, colour temperature adjustment and compensation for chromatic aberrations too. Unless you are prepared to make those adjustments to the RAW data, you will always have this issue.
Issues of colour are usually about device calibration. The monitor will only display images in the colour space it is set up for. This is usally insufficient to get a good correlation between the image file aqs displayed and the output file as printed. The answer is to calibrate all of your input, display and output devices.
At the minimum, this means colour calibrating your camera for several different light sources, your display for several different light ssources and your output file for whichever printer and paper combination you use. In truth, if you work to process your images by the numbers, it does not matter what your display shows you but you need to work in a way that does not rely on the screen display. It only converts images to the display space and the display colour space has no effect on the output colour space.
What does matter is trying to cram the information from a 16bit colour space into that of an 8bit colour space as in the case of RAW to jpeg conversions. You will be losing colour information and with it you will lose some image detail.
Tell me what icc profile setting your display shows... go to display preferences > color > make sure that the checkbox for "show profiles for this display only" is checked and then read off the display profile that is in use (it will be highlighted and there may be a choice of two or three different profiles)

  • Problem with Adobe Help Online

    Dear sir,
    Hi, My name is Palm.
    I have a problem with Adobe Help. Every time I use the function "Leyer Style" >> "Gradient Overlay".
    Adobe Help Online is often displayed without my pressing or click anything.
    It was a problem with my work.
    I have to restart the program. To work again.
    Thanks for the help.

    Thank you.
    It's excellent for this solution.
    I have solved the problem as suggested.
    Now the problem is still not found but I will monitor this issue further.

  • Problems with "Mac Help"

    My help files, especially "Mac Help", no longer work properly since upgrading to Tiger. If I open "Mac Help", for example, the help window will pop up, but the links will not work (nothing happens when I click on them) and the search feature in help will not work either (the little gray "clock" just spins next to the help bar and nothing else ever happens). Any suggestions on this one? As I'm a relatively recent Mac convert, the help feature was something that I came to rely on. Thanks!

    Hi CP,
    This is a common problem with Mac Help. When it happens, try first (quit Help) deleting this folder:
    Home/Library/Caches/com.apple.helpui
    If Help still doesn't work, try then deleting those files:
    Home/Library/Preferences/com.apple.helpviewer.plist
    Home/Library/Preferences/com.apple.help.plist
    (and this one if you find it):
    Home/Library/Preferences/com.apple.helpui.plist
    See also this KB article for more info
    - Mac OS X 10.2, 10.3: Mac Help Viewer unexpectedly quits
    and this excellent X Lab FAQ
    - Troubleshooting Help Viewer
    It seems (not sure about that), that Help caches get easily corrupted when interrupting searches instead of patiently waiting for its internet accessings etc?
    Good luck!

  • PS CS 6 & LR 4.1 problems with Raw

    There seems to be a big problem with CS6 (and LR4.1.) with some raw files. My computer has now been logged in twice by adobe support personel trying to fix the problem with no luck.
    First photoshop was not able to open Canon 5D mk3 / CR2 raw files- that got fixed and LR could not open them any more. That got fixed and the problem returned to Photoshop. The last attempt py adobe personel to fix it was poor and "reading" from a book and trying to fix it did not solve anything. I the formatted my hard drive and reinstalled both applications. It seemed to work fine - until next opening of Photoshop when it coul not open the raw files again!!  Really getting tired of this nonsense. Anyone- any ideas??
    Just to clarify I do have the latest updates on these applications...

    I had this exact same problem, but with PS 5 & LR 4.1;  then with PS 6, ACR 7.1 the same damn thing happens!  I've uninstalled PS 6, can't afford it anyway.  Tried using Adobe's DNG convert, the files "convert" to .DNG but they wouldn't open either.  So darn frustrating as the whole system worked fine 2 days ago and now freezes while trying to open anything but a JPG!  No changes to computer; MacBook Pro (unibody) 17", 8 GB RAM, 10.6.8.
    I went back to 10.6.8, PS 5, ACR 6.7 (my D4 is covered) and reset prefs for both PS & LR and now things are working again.... time to reformat this darn thing and clean it up, what a pain!
    BTW, do you or Curt know of a backup program that keeps track of serial #'s??  Having to find all those again will be a pain.

  • Problem with Adobe Help in Creative Cloud

    I'm using Mac OSX 10.9 but this problem has been here before that.
    My Adobe Help application says "No Adobe Products are currently installed." which is completely wrong. If I look at the "Local Content tab there is nothing displayed. I did have the "Display Local Help Content only" set to "yes, because it annoyed me to be taken to SLOW website whenever I clicked help. But now I have no other options and it seems to have mucked uo the help system altogether. I have changed it to "No" now so that it will display online content, but the real problem is that it does not recognise ANY of the installed CC applications.
    Any clues as to what the problem is or how I can make Adobe Help recognise my installed applications? Adobe Help has SUCKED BADLY for local help content for a long now.

    i too have issues with the help the tech sopport for Adobe. When i last tried to call i was told it would be a hour wait. Using the online chat was useless as well. Then to top things off my code for the ID theft monitering servies is not valid. Now i have to call and deal with that, there is another half a day wasted. I think its time to hack the software, YES adobe i have the .DLL files needed to have creative cloud or windows 7. Unless i get better help im going to cancle my subscription and just intall the hacks so the software still works. who needs support they are useless anyway.

  • Problems with the help menu.

    Hi. I'm a new iMac user and have had problems using the help menu on my computer. Every time I click on help and search a topic I get a blank untitled window. Nothing ever opens up in the window and then the spinning beach ball comes up. It is only in the blank window and I am still able to use the computer normally. I am unable to close or force quit the program and have to restart to get rid of it. I have called tech support and spent over an hour on the phone with no help and ended up reinstalling the operating system. Still having the same problem. Anyone have some advice or have had a similar problem?

    Welcome to Apple Discussions!
    Try reindexing the hard drive via Apple menu -> System Preferences -> Spotlight.
    Drag the hard drive into the Privacy section, and the select it in that section, and select the minus sign in the bottom left corner below the field holding the drive.
    Click then on Spotlight every half hour to wait until the Indexing status no longer shows up.
    If Help still doesn't come up entirely, try clicking on the clear jewel in the upper right corner of the Help menu. It may reveal the search field. If it doesn't, quit from the Help Viewer application menu, and then go to com.apple.helpviewer.plist and delete it. Help should then load normally.
    If it still doesn't, try repairing permissions with Applications -> Utilities -> Disk Utility.
    In the end, if that still doesn't work, let us know, and we might suggest something else.

  • Curious Problem with Images - Help required soon

    I'm working towards a Monday deadline and this problem with Pages is giving me nightmares.
    The images swap but keep the same bounding area. A logo, for example, may have in its place a screenshot.
    It is getting out of hand and I need help with this quickly.
    Thanks in advance.

    You can set the preferred address to bind the registry via the "java.rmi.server.hostname" system property, which can be set via the command line:
    java -Djava.rmi.server.hostname=127.0.0.1
    or...
    java -Djava.rmi.server.hostname=my_host
    I think you can also set the property programatically via the setProperty() method in the java.lang.System class

  • Facing problem with Value Help

  • Problem with camera help

    good morning, I have a problem with my ipad 2 camera photos, are blurry not sharp as it should, someone can help me with this please

    Be sure the camera is clean on your iPad!
    If you're stuck within an app or you've noticed a problem, simply hold both the home button and sleep/wake button at the same time. It's important to keep your fingers on these buttons until step 3.
    After a few seconds the red ‘slide to power off' screen will appear, simply ignore this. Ensure your fingers are still holding down the home and sleep/wake switch.
    Shortly after you should see the Apple logo, it's now safe to let go of the iPad's buttons. Your iPad should now boot, beware this process can take up to 15 minutes or so.

  • Weird Photoshop launching Problem with Leopard - Help!

    Program: Photoshop 10.0 from CS3 Design Premium
    Computer: Mac OSX leopard Version 10.5.1., Intel core 2 Duo.
    Problem: When I launch Photoshop I get this message: "Could not initialize Photoshop because the file is locked. Use the 'Get Info' command in the Finder to unlock the file.
    Well, I select the program icon (which is what the message is referring to as "the file") then I go to the 'Get Info' window it shows that program is not locked. I have uninstalled the program, and even the whole suite and reinstalled it a number of times, but nothing works. HELP!
    All the other programs open fine except for the InDesign which will open, but not for long before it quits. No error message pops up with the InDesign.
    HELP!!!
    LK

    Hi Folks!
    Well, I have spent a lot of time going back and forth between Adobe and Apple techs for days, and it comes down to this:
    I was told by both that I could do a clean install of the Leopard and chance that the Adobe Photoshop and InDesign will still have the same problems, or I can wait for Adobe to work on fixes for the software.
    When I originally installed the Leopard it was installed over the original Tiger operating system. I have loads of software on the computer, Quark, MS Office, CS3 Design Premium, and much more and other than some issues with my AOL everything works perfectly except the problem mentioned above with Photoshop and InDesign. AOL is working on a new software for Leopard which should come out soon. It seems that Adobe needs to do the same with Photoshop and InDesign, or make fixes for the many problem, which from I read they are trying to do.
    I would really hate to do a clean install on my computer, with all the work that comes with it reinstalling software, printer drivers, etc., just to find that Photoshop and InDesign will still have problems.
    From some of what I read from others on this string, and in other areas of the forum, it looks like people are often having problems with Photoshop and InDesign even if they did a clean install.
    If anyone had done a clean install and are still having problems, please mention it on this string.
    THANK YOU!!

  • CS2, Vista, and problems with raw files

    Hello everyone. I have recently installed CS2 with RAW updates 3.6 on my new computer, which happens to have Vista on it. The RAW files I created with my Nikon D80 are not showing in Bridge either as thumbnails or when I click on them to enlarge them.
    Does Adobe plan to address this problem through future downloads?
    Any suggestions? I may be slow to respond since I will be out of town this weekend.
    Thanks!

    I've seen some strange things happen with Photoshop Elements on Vista. Some of it worked some didn't.
    The security features of Vista are a bit too much at times and I got Elements to work by running the program with Administrator Priviledges.
    It might be worth a try. Right click on the desktop icon and select Run as Administrator ( or something similar - I'm not on a Visa PC right now)

  • FTP problems with CS5 - Help please

    I volunteer helping charity and education organisations with their websites.  One of my clients has just bought CS5 - I personally am still working on CS3 - so when I went to help them download their site first of all the set-up was quite different (why do companies fix things that aren't broken), but I got over that issue and managed to connect to the site, download and make a couple of changes. All was well!
    Two days later I went back, because they were having problems and I couldn't connect to the server.... Well, when I was on the main Dreamweaver screen  the computer said it was connecting and made all the right moves uploading files etc, but nothing on the website changed, so goodness knows where the files were going.  When I went onto the screen showing local and remote files, on the server side there was just a message saying you can't upload unless you set up a control version and the little blue plug was just greyed out.
    I don't want or need to set up a control version as it is just one person dealing with this site from one computer.
    As this is the first time I have come across 'subversion' or SVN I am a little confused. I have sent an email to the hosting company to make sure it is not a problem with their server, but won't get a reply until Monday so I thought that over the week-end I would just ask all you out there....
    Help!!

    DW is more than capable of managing your FTP tasks on its own.  Please tell us - when you connect to the remote site and then LOOK at the Remote side of the Files panel, what FOLDER names do you see?  As an ancillary question, what do you have in the Root Directory field of the Remote site definition?
